Title: Improved means for maintaining a supply of lubricating oil in the crankcase sumps ofinternal combustion engines
IPC: F16N19/00
Filed: 1944-10-06
Abstract: 591,056. Lubricating systems. BARTON, M. Oct. 6, 1944, Nos. 19155/44 and 12/45. [Class 12 (iii)] The oil level in the crankcase sump B of an internal-combustion engine of a vehicle is maintained by a pump which is interconnected with the brake pedal of the vehicle so as to be operated each time the brake pedal is actuated thereby to raise oil from a reservoir A, situated below the normal oil level in the sump, to such sump which has an overflow pipe O to return excess oil to the reservoir. As shown the pumping. is effected by applying the vacuum of the braking system, or from the induction pipe of the engine, through a brake-pedal operated valve to the rear of a spring-pressed pump plunger E which draws oil from the tank A through a tubular filter P and on release of the vacuum forces oil through a pipe F to the sump, any excess oil returning to the tank A by the overflow pipe O. The pump plunger may instead be directly actuated by a mechanical connection to the brake pedal. The pump may be an electrically driven piston, diaphragm, or gear, pump operated while a brake pedal switch is closed. According to the second Provisional Specification the pump may be operated at intervals by means of a time switch. The tank is provided with a visual oil gauge.

Abstract: 204,307. Weymann, C. T. Sept. 21, 1922. [Convention date]. Catches, automatic; stud- and-socket fastenings; multiple - bolt fastenings.- Locking means of the type comprising a nosed bolt adapted to engage a socket and be secured therein by a spring-controlled transverse pin is applied to motor vehicle doors, which, if desired, may be fitted with a number of nosed bolts engaging corresponding sockets on the door post which also carries the spring-pressed transverse pins operable from a common and distant point. An attachment plate c, Fig. 1, fixed to the door carries a nosed bolt b adapted to engage a socket d on an attachment plate h fixed to the door post, and the engagement is secured by a sliding pin e on the socket member shot by a spring k, release being effected by a lever j. Several such devices may be used as shown in Fig, 2, the securing pins e being operable for release from a central handle spindle carrying a finger p operating a three-armed lever, j, m, n linked by rods o to pin-cranks j, l whereby the arms j for operating the pins e are actuated simultane. ously. A spring k acts to retain the pins. The Specification, as open to inspection under Sect. 91 (3) (a), states that the fastening may serve to secure together two panels, or a panel in a dead sash. This subject-matter does not appear in the Specifications as accepted.

Patent GB-1369741-A (GB)
Title: Method and apparatus for forming fins on the outer surface of  tubing
IPC: B21C37/20
Filed: 1972-04-25
Abstract: 1369741 Making finned tubing; rolling NON-FERROUS INTERNATIONAL CORP 25 April 1972 [7 May 1971] 19228/72 Headings B3M and B3K In a method of forming helical fins on the outside of a length of tube of non-magnetic material, the tube is fed through a rotating finforming head while supported on a mandrel, the mandrel being restrained magnetically against axial movement with the tube. The magnetic restraint is produced by providing the mandrel with axially spaced sections of magnetic material, and by passing a magnetic flux through these sections by means of coil assemblies positioned around the mandrel. A tube 18, Fig. 1a, of indefinite length passes through straightenings and feed roller assemblies 5 and 6, through magnetic coil assemblies 20- 27, and through roller assembly 8 (Fig. 1b) to a fin-forming head 9. The resulting finned tubing is either coiled or cut to length by a flying shear 35. Each magnetic coil assembly, such as assemblies 26 and 27, Fig. 3, is provided with a coil 76 surrounded by spaced annular polepieces 78-85. The polepieces are of magnetic material and co-operate with staggered magnetic portions 57-63 of the mandrel. Spacers of non- magnetic material separate both the polepieces 78-85 and the portions 57-63. The flux produced by the coils opposes any forces tending to move the mandrel axially. Should the mandrel move axially, a sensor 94 detects this movement and either produces a warning signal or switches off the apparatus. The fin-forming head, Fig. 7, includes skewed roller units 137 which are biased by springs away from the tube. Rollers 144 act against the outside of carriers 139 for the units to prevent movement of the units outwardly. However, if a sleeve 113 carrying the rollers is shifted axially, the cammed outer surfaces of the carriers allow the units to be retracted from the tube. The portion 44 of the mandrel within the units 137, Fig. 3, may be connected by a swivel joint 54 to the portion 56 of the mandrel, to allow rotation of the portion 44. The head itself is driven rotatably by an hydraulic motor 130, Fig. 1b, and a toothed belt 128. The head is carried on longitudinal guide rods for limited movement axially of the tube, to allow for any variations in the speed of advance of the tube. Thus, if the tube is advanced too quickly, the head is moved towards the right. This actuates a control valve supplying fluid to the motor 130, and the rotational speed of the head is increased. The speed of the motor can be controlled automatically, or by a manual control valve (Fig. 6, not shown). Should the head move axially an excessive amount, a limit switch is operated to shut off the apparatus.

The projection 32 may be replaced by a supporting cone which is used to lift out the solid phase at the end of the separation.

Abstract: 498,830. Hand - irons. ALADDIN INDUSTRIES, Ltd. July 13, 1937, No. 19442. Convention date, July 17,1936. [Class 138 (ii)] Relates to hand-irons for burning heavy liquid oil fuel. In the form shown in Figs. 2 and 8, the oil is forced from the reservoir 18 by air pressure created by a manuallyoperated piston pump 28 housed in the handle through a tube 37 having a restricted passage and a valve controlled by a knob 50. The oil is vaporized initially by the combustion of methylated spirit in a dish 60 surrounding the tube 37 and having a lip 61 accessible from outside the iron for filling the dish when the iron is up-ended as in Fig. 8. The vaporization is continued by the heat from the burner and sole plate acting on the tube, and the gas is mixed with air and passes through a bent tube 55 to a rose burner 56. A pressure relief valve and a filling aperture are provided in the reservoir. In the form shown in Fig. 17, the tube is provided with two coils of which one is subjected to the heat from the burner for continuing the vaporization of the oil which is started by the passage of the oil through the other coil 77 which is arranged in a chimney 100 above a recess 102 in which the methylated spirit is burnt. When the vaporization is proceeding satisfactorily, the chimney is closed by a damper 105 actuated from outside the iron to prevent cold air sweeping past the coil 77. The valve chambers controlling the supply of fuel are provided with pins for cleaning the gas nipples operated by control devices from the outside of the iron.

Abstract: 2 (iii) <PICT:0628674/IV (b)/1> Alkylated olefins are produced by continu ously feeding calcium oxide, and a mixture of 2,3-dimethylbutene-2 and an alkyl halide in counter-current through a reaction zone at a temperature of the order of 200-300 DEG  C. Pressure is substantially atmospheric.  Methyl chloride, iodide, and bromide, ethyl chloride, and isopropyl chloride, are suitable alkyl halides.  Removal of peroxides or inhibiting their formation is effected as in Specification 577,122, which also describes the preparation of a suitable lime.  A reaction tube 10 is charged with lime from hopper 12 and is heated by a medium circulating through jacket 16 and heater tube 20 containing a heater 18.  The olefin and alkyl halide enter tube 10 through pipe 34 and distributer 36, being preheated in tube 38.  A stirrer 30 mixes the reactants, solid reaction products being discharged by plunger 46 into hopper 48, and vapours leaving by line 40 to be condensed and recirculated as desired.  The lime is fed at above 110 per cent of the theoretical amount required.  3-8 mols. of methyl chloride are used to 6 mols. of 2,3- dimethylbutene-2 to yield triptene, which may be hydrogenated to triptane.
